The SAT has taken a lot of criticism over the years. This appears to be a response. One side-effect, suggests NPR, is that ti may make the test-prep industry slightly less lucrative. There are two major strands. The first is the introduction of a set of free study tools to level the playing field for less-affluent students." SAT and Khan Academy will partner to produce the online materials, and the Boys & Girls Club of America will focus on in-house tutoring and support. This is an instance of the Triad Model. The second addresses the test itself, which will be revamped. "The essay section will now be optional, and students will no longer be penalized for wrong answers. And obscure SAT words that are little used in everyday conversation will be dropped. The emphasis now will be on relevant, useful vocabulary in context."
